How do you interpret the results from a local I-Tasser run?

Hello,
This is the first time I am using I-Tasser. I have made efforts to understand how to run the software locally and interpret the output, but I don't think I understand the process well enough. If I could get help with the workflow, that would be great.

I first downloaded and installed the program. Then I executed runI-Tasser.pl, which ran for about 8 hours for a protein of about 300 AA. I was expecting a series of PDB files at the end but didn't see any. There appeared to be some PDB looking files (e.g. init.wMuster, init.wPPAS) but given the name, these may be template files rather than modeled structures.

Right now, I'm executing runMuster.pl, thinking that I need to run these scripts sequentially, but I am not sure.

Any help you can provide would be sincerely appreciated.

Thanks.
